OSI Model Session Layer It is a fundamental concept in the world of computing and communications. This layer provides the mechanisms necessary to establish, manage, and terminate connections between applications on network devices. In this article, we will explore the basic concepts of Authentication and Authorization Protocols which are essential for the security of communications in the OSI Model Session Layer. Understanding these concepts is essential for any professional in the networking field, as they form the basis of information security in network environments. So get ready to immerse yourself in the fascinating world of security! OSI Model Session Layer!

– Step by step -- Session Layer of the OSI Model Basic Concepts of Authentication and Authorization Protocols

• The Session Layer of the OSI Model It is the third layer in the OSI architecture and is responsible for establishing, maintaining and terminating connections between two applications on the network.
• In this layer, we define the basics of authentication and authorization protocols which are essential to guarantee security and access control to network resources.
• La authentication refers to the process of verifying the identity of a user or device, while the authorization It is responsible for determining what resources or services an authenticated user or device is allowed to use.
• The authentication protocols such as Kerberos, OAuth and OpenID, are used to verify the identity of users and guarantee security in communications.
• Furthermore, the authorization protocols such as RADIUS and TACACS+ are responsible for controlling access to network resources, determining what actions authenticated users can perform.
• Understand the basics of authentication and authorization protocols It is essential to design and maintain secure and efficient networks, protecting data and resources from external and internal threats.
